(Intermittent) Authentication Ticket is Invalid - When Attempting to Join ANY Server

First issue - get popup when attempting to login after being disconnect results in the error/popup at server selection screen. This popup prevents joining a server as you normally would.

Second issue (related? or not) - when the popup no longer displays and I am able to join, character/mount is unable move when loaded into the server. After waiting for a few minutes, multiple game restarts and reloads in addition to using /stuck, the situation is still unresolved. Sadly, another case of lost gear and loot due to an in-game bug.

Any response to this issue? It's not happening on a regular basis, but it is interrupting gameplay and leaving characters stranded in game while we struggle to log back in. It's hard to replicate the issue as I don't even know what is causing it.

After multiple attempts to login by restarting rend, restarting steam, and restarting PC (and getting the same message), I decided to attempt a reinstall. Got the same error/popup for 5-10 minutes while trying to join.

Finally, at random, the messages stopped and let me join the server... What gives?
